"For every action, there is an equal and opposite reaction"... The Dems brought this upon themselves.

Newton's laws of motion are often stated in layman’s terms for simplification and easy recollection as:

First Law: "An object in motion will stay in motion and an object at rest will stay at rest unless acted upon by an external force" or "A body persists in a state of uniform motion or of rest unless acted upon by an external force."

Second Law: "Force equals mass times acceleration" or "F = ma."

Third Law: "To every action there is an equal and opposite reaction."

[edit] Explanation

First law
There exists a set of inertial reference frames relative to which all particles with no net force acting on them will move without change in their velocity. Newton's first law is often referred to as the law of inertia.

Second law
Observed from an inertial reference frame, the net force on a particle is equal to the time rate of change of its linear momentum: F = d(mv)/dt. Since by definition the mass of a particle is constant, this law is often stated as, "Force equals mass times acceleration (F = ma): the net force on an object is equal to the mass of the object multiplied by its acceleration."

Third law
Whenever a particle A exerts a force on another particle B, B simultaneously exerts a force on A with the same magnitude in the opposite direction. The strong form of the law further postulates that these two forces act along the same line. Newton's third law is sometimes referred to as the action-reaction law.
